DOOR FASTENER- Application filed August 11, 1923. Serial No. 656,852.

To all whom it may concern:

Be it known that I, CARL HOFFMAN, a citizen of the United States,residing at Allentown, in the county of Lehigh and State ofPennsylvania, have invented certain new and useful Improvements in DoorFasteners, and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to door fasteners and particularly toimprovements in a door fastener adapted for locking a door in eitherclosed or partially open position.

An object of this invention is to provide a keeper and a'latch mountedon a door and jamb adapted for locking the door in closed position andprovided with operating means for the latch adapted for association withthe keeper to lock the door in partially open position.

Another object of the invention is to pro vide akeeper and latch'for anoutwardly opening door adapted to lock the door in closed position inwhich the latch is provided with an operating member adapted for lockingcooperation with the keeper for holding the door in partially openposition.

The invention further includes the pro vision of a U-shaped memberhaving one leg pivotally connected with the latch and the other legadapted for sliding movement through the keeper to guide it into lockingcooperation with the keeper for fastening the door in partially openposition.

The invention includes other objects and improvements in the details ofconstruction which are particularly pointed out in the followingdescription'and claims and shown in the accompanying drawing in whichFigure 1 is a perspective view of an outwardly opening door showing mydevice mounted on the door and jamb and positioned for locking the doorpartially open. Figure 2 is a horizontal section through the door andjamb showing the invention in plan with the parts in unlocked positionand the handle member shown in dotted lines in its position preparatoryfor the partial opening of the door, and Figure 3 is a horizontalsection through the door and jamb showing a plan of the invention withthe parts in position to lock the door closed.

1 in ic t s the j arch and 2 the door opening outwardly therefrom whichis provided with a plate 3 rotatably supporting a spindle 4 from whichprojects the latch 5 adapted for locking cooperation with the keeper t3mounted on the door jamb. The keeper is formed with a longitudinallyextending recess 7 in the body portion thereof and an opening 8communicating with said recess as shown in Figure 2. The keeper isprovided with openings at 9 adapted to receive a looking pin 10 providedwith a chain connection 11 secured under one of the attaching screwsmounting the .keeper on the jamb. A U- shaped member 12 has one of itsfree ends or legs pivotally mounted in the spindle 1 as indicated at 13and forms an operating handle for rotating the spindle to engage ordisengage the latch from the keeper. The member 12 is adapted forsliding cooperation with the keeper, and the free end being insertedthrough the opening 8 and thus coupling the member and the keeper. Whenthe door is opened as far as engagement be tween member 12 and keeper 6will permit, pin 10 is positioned to prevent disengagement of the member12 from the keeper thus effectively fastening the door in partially openposition. An opening 14 is formed in the spindle L to receive the freeend of the 'member 12 when the parts are in unlocked position, as shownin Figure 2, and serves to limit movement of said member toward the doorthus. obviating any likelihood of the same being scarred.

Figure 3 shows the latch 5'in engagement with the keeper 6 in itsposition for locking the door in the closed position. By using themember '12 as an operating handle the latch may be rotated from thelocked position in Figure 3 to the unlocked position as shown in Figure2, and upon the movement of the member 12 into the position shown indotted lines in Figure 2 the parts are ready for the movement of thedoor into partial open position.

It is to be noted that this invention is particularly adapted for usewith doors opening outwardly and includes a slngle member adapted to actas an operating means for the latch and additionally to cooperate withthe keeper for fastening the door in partially open position. Whenpositioned as shown in Figure 1 for maintaining the door ajar, themember 12 effectual- 1y maintains the latch 5 in inoperative position sothatno. damage will be done to either latch or keeper should the pin10,be removed and the door slammed shut.
